Dorman Intake Manifold, Valve Cover & PCV Tube Kit for GM 1.4L Ecotec — Redesigned PCV Interface, OE-FIX for Buick/Chevrolet

Dorman's 615-380KIT is a complete intake manifold, valve cover and PCV tube assembly engineered as an OE FIX for GM 1.4L Ecotec engines to stop recurring PCV valve failures. This kit replaces the commonly failing intake manifold, valve cover and PCV tube on select Buick and Chevrolet models and includes a redesigned intake manifold intended to resolve the root cause of repeated PCV valve breakdowns. It’s sold as a single repair package so technicians and DIYers can address all related damage at once instead of swapping individual parts and returning when another component fails.

What parts are included and why are they bundled?

The kit contains an intake manifold, a matching valve cover and a PCV tube assembly. These components are often damaged together: a failing PCV valve can overload the manifold and valve cover, and the plastic PCV tube frequently breaks during removal.

• Intake manifold with redesigned PCV interface to reduce failure points
• Valve cover matched to the updated manifold to ensure proper sealing
• PCV tube assembly to replace brittle or cracked tubing
• Sold as a single package to avoid multiple repair visits

How does the redesign improve long-term performance?

The intake manifold in this kit has been re-engineered to address the repetitive failure mode seen in the original equipment. The updated geometry and connection points reduce stress on the PCV valve and surrounding housings, helping to prevent premature failure.

• Reinforced PCV interface to limit wear on the valve
• Reworked sealing surfaces to reduce vacuum leaks
• Materials selected to resist oil and heat-related degradation

Which vehicles and model years does this kit fit?

This Dorman kit is designed for General Motors 1.4L Ecotec applications on specific Buick and Chevrolet models. Fitment varies by year and trim, so always verify using your vehicle details before purchase.

• Buick Encore: 2013–2019
• Chevrolet Cruze: 2012–2015; Cruze Limited 2016
• Chevrolet Sonic: 2012–2018
• Chevrolet Trax: 2013–2019

What symptoms can this kit help address?

When the PCV system or its housing fails, owners often see oil consumption, rough idle, or engine codes related to vacuum or emissions. Replacing the manifold, valve cover and PCV tube together removes worn components and re-establishes proper crankcase ventilation and sealing.

• Reduces oil consumption linked to PCV malfunction
• Helps restore steady vacuum and smoother idle
• Resolves related diagnostic trouble codes caused by leaks or valve failure

Who is this for? This kit is intended for vehicle owners, independent mechanics and fleet technicians working on GM 1.4L Ecotec engines that are experiencing repeated PCV valve or manifold-related problems. It’s a practical solution when the original intake manifold and valve cover show age-related cracking or when the PCV tube has broken during service. If you need a durable replacement that addresses the known weak points in the OE design and prefer a single-purchase repair, this Dorman OE FIX kit is built to replace the complete assembly and limit future callbacks. Always confirm fitment for your exact vehicle trim before ordering using the vehicle lookup tool.
